Abstract (en)
A state monitoring device monitors a state of a robot capable of playing back a predetermined operation. A time-series data acquirer acquires time-series data of state signals for a period of time from the timing of an acquisition start signal indicating a start of acquisition of a state signal reflecting a state of the robot to the timing of an acquisition end signal indicating an end of acquisition of the state signal. The time-series data is stored in association with timing information indicating the timing of acquisition and playback identification information identifying a playback operation of the robot. A dissimilarity calculator calculates dissimilarity between reference data based on the time-series data acquired in at least one operation and comparison data based on the time-series data acquired in an operation performed after the acquisition of the time-series data pertaining to the reference data. The robot state evaluator uses the dissimilarity as an evaluation quantity to evaluate the state of the robot.
